I have also had a similar idea a few days ago.*1
I would like to know whether you guys think it makes
sense to go even further and have also this kind of
calls for attributes and other potential "nodes" in 
our parse tree. I would think so.

Now the question remains if this approach should substitute
the event base stream that built the bottom layer of
our XAPI-J discussion. I think the event based approach
should still form the base. Many people, I believe,
feel still very comfortable with it.
